Tariff ruling: Meet the Trump-appointed Supreme Court judges who went against him

 At the heart of the case was whether Trump could use emergency powers under a national-security law to impose broad tariffs on imports. The Supreme Court ruled that the statute did not authorise such sweeping action. It held that tariffs are essentially a form of taxation, and under the Constitution, the power to impose taxes rests with Congress. At the heart of the case was whether Trump could use emergency powers under a national-security law to impose broad tariffs on imports.
